我们可以在订阅计划中应用两张优惠券吗？

Question

  \Stripe\Subscription::create([
            "customer" => $customer->id,
            "items" => [
                          [
                             "plan" => $aplan_id,
                             "quantity" => $totalQuantity
                          ],
                          [
                             "plan" => $kplan_id,
                             "quantity" => $kidsQuantity
                          ],
                        ],
            "coupon" => $selectedDiscountId, // recursive discount is set in percentage
            "coupon" => 'one-time-free',// one time discount on a plan
  ]);

If customer purchased 3 items one should be free as 'coupon' => 'one-time-free' is already set to flat amount and above coupon 'coupon' => $selectedDiscountId, is set to recurring discount in percentage.

Next time only first coupon is applied as it is recurring coupon it should be, and second one should not.

1. first coupon is for one time discount 'flat amount'
2. second coupon is for recursive discount in percentage
